Just completed all highway driving at an average speed of 64MPH in my Cobra with 2 stroke tcw3 in the gas tank at 3oz per 5 gallons. My gas mileage was an incredible 17mpg at 104 miles and 21mpg at 170 miles. My best mileage before adding tcw3 had been 15.5mpg. Using Costco brand gas. I continue to experience quicker starts, smoother idling, and improved throttle response.
